TABLE 2.
Summary of the best fitting model for the full dataset (i.e. including experiments without body mass data, Table 1, re‐fitted using REML) describing variation in rates of plasticity (λ E ) in thermal tolerance among different classes of ectothermic animals. ‘Slope at end’ is the slope of the estimated exponential decay function at the final measurement. The amount of variance unaccounted for by fixed effects (I 2, %) explained by the different random effects are given (total I 2 = 99.9%). Pseudo‐R 2 for the model was 0.18
